TO INSTALL:
System Voltage Requirements
1. Measurepanelvoltage,L-N,todeterminethesystemvoltage.SystemvoltagemustnotexceedthespeciedmaximumcontinuousRMSvoltageontheSPDdevicelabel.
Location and Mounting
1. LocatetheSPDdeviceascloseaspossibletothebranchcircuitbreakerpanel.ConnectionleadlengthbetweentheSPDdeviceandcircuitbreakerboxshouldbeminimalfor
bestprotection.ThelocationshouldalsopermitgoodvisibilityoftheSPDdevice’sdiagnosticlights.
2. Removethecircuitbreakerpanelcoveranddeterminethebreaker-panelwiringentrypointrelativetochosenlocationoftheSPDdevice.
NOTE:SincethecircuitbreakerpanelandtheSPDunithaveoverlappingcovers,installationshouldallowatleastoneinchofclearancefromtheedgeofthecircuitbreaker
panelcover.
3. Forsurface-mountcircuitbreakerpanels,theSPDdevicemaybeconnectedusingrigidconduittoanyconduitknockouthole.
4. Fornon-surfacemountinstallations,securetheSPDtothesupportstudinthewallbycuttinga6x6-inchmountinghole.
5. RemoveSPD’scoverandconnect3/4-inchexibleorrigidconduitbetweencircuitbreakerboxandtheSPD.
